The present invention .relates to button Structure of the typeY in whicha. sheet metaly part has prongs struck therefrom for insertion through afabricto be clinched to secure the kind described in which are includedmeans for strengtheningv the portion of theV sheet metal from which theprongs havev been cut. Another object of the invention is to provide yapronged sheet metal button structure in which a section of the sheetbetween the rongs cooperates with the prongs in hol ing a fabricattached from disengaging movement. Other objects and advantages' willappear from the drawings and from the following tion of--forms of buttonstructures used to illustrate the invention, and the invention alsoconsists in the parts and combinations of parts particularly set forthin the claims.

In the drawings, in which like reference characters refer to like partsthroughout, there is shown for purposes of illustration variousembodiments of the invention in which Figure 1 is a plan view of afabric piece and a button attached thereto, Figure 2 is a reverse planview of the fabric showing attaching means, Figure 3 is a verticalsectional elevation view of a button attached to a fabric, Figure 4 is aplan view of a fabric piece with the button part of a button attachedthereto, Figure 5 is a reverse plan view with the fabric in part eutaway, Figure 6 is a view similar to that of Figure 4 showing analternate form of attachment, and Figure 7 is a view similar to that ofFigure 2 but without the clinching ring shown in Figure 2.

In Figures 1 to 4 of the drawings a bottom part 1 of a button is ofsheet metal and is cup shaped with V-shaped cuts 2, 2 made in the bottomthereof to form V-shaped prongs 3, 3 positioned diametrically oppositeeach other, said cuts 2, 2 defining triangular openings 4, 4 in thebottom of part 1 when said prongs 3, 3 are bent therefrom. Said openings4, 4 are adjacent each other with respective sides of cuts 2, 2 parallelto each other and with a strip 5 of the metal of part 1 left betweenthem. In the preferred form of assembly to a fabric a ring 6 is providedthrough the central opening of which the prongs 3, 3 extend after beinginserted through a piece of fabric 7. The prongs 3, 3 are then clinchedor bent over the ring particular descrip-` 6 and their ends pushed intosaid fabric 7 to bind the fabric securely to the button structure,particularlyy against the edges of said triangular shaped openings 4, 4at the edges of said strip l5 and against the 'other edges of saidopenings. By thisarrangement there is prevented any movement of thefabricv such as will allow the release of the fabric from said prongs 3,3. Thev top cap 8 fits onto said bottom part 1 and binds in place thefabric covering 9 which extends over the top and has its edges foldedaround the annular edge of `cap 8.

In Figure 5 isV an alternative embodiment in which a bottom part 1 hasformed therein two prongs 3', 3 whose bases are oppositely positionedwith respect to each other, said prongs 3', 3 being inserted through afabric 10 vand through the central opening of a metal ring 11 over whichthey are `bent and clinched into the fabric on the outside of the ring.In this form the ring 11 extends over the triangular openings 12, 12formed when said prongs 3', 3 are cut and binds the fabric tightlyagainst the edges of said openings 12, 12.

. In Figure 6 is illustrated the same form of structure as in Figures 2,3 and 4 except that no ring is used and the prongs 3, 3 are bentinwardly after being inserted through the fabric 7 and again insertedthrough the fabric and clinched thereon. In Figure 7 is again shown thesame form as in Figures 2, 3, 4 and 6 and without the use of theclinching ring. In this form the prongs 3, 3 are bent outwardly as inFigures 2 and 3 but clinched directly against the fabric 7 without theuse of the interposing ring.

Although I have set forth and described various embodiments of myinvention, it is obvious that various changes, substitutions andomissions may be made in the arts and combinations without departing romthe spirit of the invention.

Having thus described my present invention, I claim 1. A buttonstructure comprising a top section, and a bottom section of sheet metalprovided with laterally spaced apart prongs cut from themetal of saidbottom sectlon, with a strip of said bottom section between theincisions of said prongs, the points of said prongs being oppositelydirected in the surface of said bottom section.

2. In a button structure a fastening portion comprising ajsheet metalpiece having V-shaped cuts therein spaced from each other laterally andhaving a strip of ksaid sheet metal piece between the incisions of saidprongs with the points ofthe Vs point- Y ing in 'opposite' directions.

3."In a button structure a fastening'por-V tion comprising a sheet metalpiece having yV-shaped cuts therein spaced apart laterally with thepoints of the Vs directed op' positely, and a strengtheningv bar betweenthe sides of adjacent V-cuts unitary with said sheet.'

v 4, In vabutton structure, avfa'stening 'portion Vcomprising a sheetmetal piece providedwith laterally adjacent V-shaped cuts to form prongsoppositely directed in the l surface of said piece and a strengtheningtion of sheet metal provided with prongs cutrfrom ywithin the confinesthereof and adapted to be bent away from the'surface of said sheet metalvsection and over the edge of said ring member. 6. In a buttonstructure, a fastening portion `comprising a ring member, anda sectionofsheet metal provided with prongs cut from within the confines thereofand adapted-to be bent away from the surface of said metal section andto extend through the opening' of said ring and to'bebent. over the sideof said ring. j

7L A button structure comprising a ring member, and a section of sheetmetal provided with V-shaped cuts therein spaced from each otherlaterally with the points of the Vs extending in opposite directions andwith a strengthening andbinding strip left between the sides of adjacentVs, said V- cutsdefining prongs adapted to be bent away from thesurfaceY of said ysheet andto be inserted through a fabric and bent overthe edges of said ring when placed on said fabric on an oppositel faceto said sheet metal section to bind saidy fabric securely between saidsheet section 'and said ring, and said strengthening Vand binding stripadapted by its position between the V-cuts to hold the fabric adjacentthereto against substantial ieXure through the .openings left at saidprongs.
